Submit  not wokring in IE and second drop down disappears on submit

I am wokring on a PHP script that has forms and submit buttons on it. The script works fine with the dropdown boxes. I am getting the desired results out of it. The only problem is the submit button is not wokring in IE and when I press second submit button on the page the second drop down disappears. I need help with this. And also if you can show me the way on how I can keep the selected values to be there even on form submit it will be great.

@mysql_select_db($database) or die( "Unable to select database");
$query="SELECT distinct chassis_vendor FROM chassis";
/* You can add order by clause to the sql statement if the names are to be displayed in alphabetical order */
$result = mysql_query ($query);
<form name="vendor" method="post">
echo "Please select the Vendor: ";
echo "<select name=name>Chassis Vendor</option>";
// printing the list box select command
while($nt=mysql_fetch_array($result)){//Array or records stored in $nt
echo "<option>$nt[chassis_vendor]</option>";
/* Option values are added by looping through the array */
echo "</select>";// Closing of list box 
<input id="submit" type="submit" value="Submit" name="submit"/>
	$vendor = $_POST['name'];
	$query1="SELECT chassis_name FROM chassis where chassis_vendor='$vendor'";
	$result1 = mysql_query($query1);
<form name="name" method="post">
echo "Please select the Chassis for $vendor: ";
echo "<select name=vendor>Chassis Name</option>";
echo  "<option>$nt1[chassis_name]</option>";
echo "</select>";
<input name="submit1" type="submit" id="submit1" value="Submit"/>
	$name = $_POST['vendor'];
echo "Configuration for $vendor $name is as below:";
